The person who reads your results is not a machine.

Notation used for entering data to a computer or a calculator via the command line is not suitable for communicating with human beings. A human reader deserves better than old FORTRAN notation. This notation does not belong in a graph which you, as a human, will read. The notation is archaic cruft in the context of graphical presentation. Programs were submitted on punch cards, with one FORTRAN statement per card, for overnight processing. The computer, such as an IBM 360 and its associated equipment, filled most of the room. Scale marks such as 5.00E-05 are suitable for communicating with a computer in FORTRAN language. Click on the image for original color graph.

The scale marks are rotated so that more effort is required of the reader: not nice. Has odd scale marks which suggest a mathematical mystery, but which are unintentionally generated by software. Scale marks 1, 11, 21 for the horizontal axis are distracting and not helpful to the reader. They are illustrative of graphical presentation errors. These graphs were submitted by students as part of assignments and project reports at several universities. Suggestions for dedicated graphics software are given at the bottom. By contrast, a poor graph can cause nausea, headaches, and distress. Good data display also encourages the reader to understand as well as to appreciate your results. A good graph is a way to offer kindness to the reader. The reader is as likely to suffer deadline pressure, fatigue, and stress as you, the writer. Remember that your graphs are to be read by a human being. R., The visual display of quantitative information, Graphics Press, Cheshire, Conn. An introduction to graphical presentation is given by Tufte, E. A good graph clearly presents an idea to the reader without the need to excessively refer to the text for basic definitions. Graphs and diagrams enable the engineer or scientist to communicate quantitative material to others. We will try to post lab reservations in advance so you can adjust your schedule for using the lab accordingly.Improving Graph Quality: Graphical Presentation Abominable graphs Improving Graph Quality: Graphical Presentation Woe in graphing and how to do better, even to excel. Also, if a class is being taught in the lab, please be quiet and do not interrupt the class. In those cases, you must vacate a computer if it is needed by a member of the class that has the lab reserved. Occasionally the lab will be reserved for classes or classes will have priority access to the computers. If you are using a computer for non-school-related activities (e.g.: playing games, sending personal e-mail, recreational web browsing), please offer to let students who are waiting for computers to do schoolwork use it.ĩ. Please use the computers with the scanners attached for scanning only, unless there are no other open computers in the lab.Ĩ. The staff would much rather show you how to use a piece of equipment than replace or repair it if you break it.ħ. If you do not know how to use a piece of equipment, ask someone. Do not leave documents lying on the tables or on the printer.Ħ. If you print something, either take it out of the lab with you or place it in the recycling bin. Do not use any lab equipment for illegal activities (e.g.: pirating software).ĥ. If your food or drink damages a computer or peripheral, you must pay to repair or replace what you damage.Ĥ.

Food and drink are not allowed in the lab. The lab is for the use of School of Chemical & Biomolecular Engineering students only.ģ. Any violations of Institute policies or the law will be reported to the proper authorities.ġ. Note that failure to abide by these policies can lead to loss of access to the computer lab.
